Datapack Support | MariesLib Wiki

MarieLib is built to be extended through standard Minecraft datapacks. Consuming mods expose datapack directories under their mod id.

All files live under:

data/<your_namespace>/<modId>/

For Nourished (modId = nourished):

data/mypack/nourished/source_classifications/my_foods.json

📁 Directory Overview

🥕 Source Classifications

Path: data/<ns>/<modId>/source_classifications/<id>.json

Maps a specific item or item tag directly to a value key.

By item

{
  "marie_schema_version": 1,
  "value_key": "vegetables",
  "item": "farmersdelight:tomato",
  "amount": 0.08
}

By tag

{
  "marie_schema_version": 1,
  "value_key": "proteins",
  "tag": "#farmersdelight:foods/cooked_meat",
  "amount": 0.10
}

Field	Required	Description
`value_key`	✅	Target value key
`item`	One of	Specific item ID
`tag`	One of	Item tag (prefix with `#`)
`amount`	✅	Contribution per consumption (0.0–1.0)

🔌 Compat Entries

Path: data/<ns>/<modId>/compat/<id>.json

{
  "marie_schema_version": 1,
  "mod_id": "examplemod",
  "category": "FOOD_MOD",
  "mappings": {
    "examplemod:mystery_fruit": "fruits",
    "examplemod:protein_bar": "proteins"
  }
}

🌿 Source Families

Path: data/<ns>/<modId>/source_families/<id>.json

Extend keyword classification with custom keyword-to-value mappings:

{
  "marie_schema_version": 1,
  "families": {
    "vegetables": ["gourd", "squash", "yam"],
    "proteins": ["jerky", "patty", "schnitzel"]
  }
}

🔒 Module Locks

Path: data/<ns>/<modId>/module_locks/<id>.json

Lock config modules server-side so players cannot override them:

{
  "marie_schema_version": 1,
  "locked": ["enableEffects", "enableDecay"],
  "server_only": ["bonusEffectThreshold"]
}

💡 Tips

Test with /reload then /<modId> reload — no restart required.
Prefer tags over individual items when possible.
Run /<modId> diagnostics after adding datapack content.
Use /<modId> schema <type> to print valid JSON templates.
